for Jews in the latter half of the 1940s - examining resettlement and migration patterns enabling a stronger understanding of the diurnal complications of Jewish life in the postwar period. Robert Cohn examines the brief window in time between 1945-46 where some Polish Jews had not yet been defeated by despair and aimed to return to their previous homeland - through this narrative he illuminates

PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability
Premium Action potential
Eliciting (Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? Depolarization has to do with surfaces becoming more negative or positive and reaches a certain point called a threshold. When the threshold is reached‚ an action potential is initiated. 2. What was the threshold voltage in Activity 1? The threshold voltage in Activity 1 was 3.0. 3. What was the effect of increasing the voltage? How does this change correlate to changes

Glomerular Filtration Activity 1: Effect of Arteriole Diameter on Glomerular Filtration 1. Compare this data with your baseline data. How did increasing the afferent arteriole radius affect glomerular filtration rate? >>Increasing the afferent arteriole radius pushed the glomerular pressure‚ the glomerular filtration rate‚ and the volume of urine to be higher than the baseline data. Increasing the afferent arteriole radius increased the glomerular filtration rate. 2. Under

Fischer Lab Time/Date: 7:00 PM/Wednesday Activity 1 Metabolism and Thyroid Hormone Part 1 1 Which rat had the fastest basal metabolic rate (BMR)? The normal rat had the faster basal metabolic rate‚ because it was not missing its pituitary gland or its thyroid gland. 2 Why did the metabolic rates differ between the normal rat and the surgically altered rats? How well did the results compare with your prediction

Skeletal Muscle Physiology Activity 1 1. Skeletal muscle fiber- long‚ cylindrical cell with multiple oval nuclei arranged just beneath the sarcolemma Motor unit- all of the muscle cells controlled by a single motor neuron Skeletal muscle twitch- a single stimulus-contraction-relaxation cycle in a skeletal muscle Electrical stimulus- uses an electrical current to cause a single muscle or a group of muscles to contract Latent period- the time between the stimulation of a muscle and the start

Exercise 2: Skeletal Muscle Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1. During a single twitch of a skeletal muscle You correctly answered: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. This phenomenon is known as

Activity 1 1. Size and concentration of the solute 2. It was too large to pass‚ as predicted 3. I predicted that the glucose would diffuse since it is small enough but the albumin is much too large to pass through the membrane. The experiment produced this result. Activity 2 1. Neither way requires ATP but facilitated diffusion requires carrier protein molecules for diffusion to occur. 2. By increasing the number of carriers more glucose can pass at a time increasing the rate‚
